JOSEPH HOUGH, OF BUOKINGHAM, AND JACOB MOORE, OF BART, PENNSYLVANIA.

CAR-BRAKE.

. Specification of Letters Patent No. 22,291, dated December 14, 1868.

To all whom it may concern:

Be it known that we, JOSEPH HOUGH, of Buckingham, in the county of Bucksand State of Pennsylvania, and JACOB MOORE, of Bart, in the county ofLancaster, in the same State, have invented a new and ImprovedRailroad-Oar Brake; and we do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, in which-Figure 1, is a vertical longitudinal section of a car truck with ourimproved brake applied to it. w, m, Fig. 3, shows the plane of section..Fig. 2, is a vertical transverse section of ditto taken in the line 1y, Fig. 3. Fig. 3, is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable those skilled in the art to fully understand and construct ourinvention we will proceed to describe it.

A, represents a rectangular frame in which the axles B, B, of the wheelsO, are placed as usual. In each side of the frame A, two levers D, D,are placed, said levers working on fulcrum pins (1. To the lower end ofeach lever D, a shoe E, is attached, said shoes being below thehorizontal plane in which the axles B, B, are placed, as shown clearlyin Fig. 1. To the upper end of each lever D, a horizontal slide F, isattached, by a pivot or pin Z). These slides F, are fitted in grooves c,in the upper part of the frame A, see Fig. 2,, and two slides at eachside of the frame shown in Figs. 1 and 3. To the outer end of each slideF, and to its under side a shoe G, is attached. See Figs. 1 and 2. Thelower ends of the levers D, at opposite sides of the'frame A, i areconnected by bars H, H, and these bars are connected by rods I, I, tothe lower ends of two levers J, J, which are secured in a longitudinalbar K, by fulcrum pins (2'. To the upper end of each lever J, a rod 6,is attached, and the inner ends of these rods are connected to ahorizontal lever L, near its center and at opposite sides thereof. Toeach end of the lever L, a rod M is attached. See Fig. 3.

From the above description it will be seen that by drawing outward therods M, as indicated by the arrows 1, the lever L, rods 6, and levers J,will be moved in the directions indicated by their respective arrows,and the bars H, and levers D, will be moved as indicated by the arrows3, and the shoes IE, will be pressed against the wheels C, at the sametime the slides F, will be moved in the direct-ion indicated by thearrows l, and the shoes G, will be pressed against the upper parts ofthe wheels and directly opposite the shoes E. Both shoes E, G, of eachwheel it will be seen are operated simultaneously and as they press uponthe wheels at opposite sides, the axles will not be subjected to anyundue strain and a greater amount of friction will be produced than ifone shoe only were applied to each wheel.

The within described arrangement of levers and slides is exceedinglysimple, but little power is lost during its transmission from the rodsM, to the shoes F, G, and the device may be applied at a reasonablecost.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent, is, l

The arrangement and combination of the slides F, and levers D, J, as andfor the purposes here-in shown and described.

JOSEPH HOUGH. JACOB MOOREI
